XRD patterns for (Cd_1−xZn_x)₃As₂. Panel (a): Powder XRD patterns for x = 0, 0.07 and 0.14 for 25° < 2θ < 36°. The characteristic peaks of (231)_I, (233)_I and (237)_I for a body-center structure and (032)_P for a primary structure are labeled. Panel (b): Powder XRD patterns for x = 0.38, 0.52 and 0.58 for 31° < 2θ < 37°. The peak of (032)_P occurs for x = 0.38, while the peaks of (240)_I and (244)_I occur for x = 0.58. For x = 0.52, we observed two sets of peaks, which indicates the batch has the mixture of two types of crystals. The (100) peak of cadmium at 34.5° occurs in all the XRD patterns with no shift. Panel (c): The diffraction pattern of the (112)_I plane for α − Cd₃As₂ and α − Zn₃As₂. Panel (d): The diffraction pattern of the (022)_P plane for (Cd_0.87Zn_0.13)₃As₂.
